MEYNCKE I PIPE LINING' MACHINE Filed Maron '1. 1932 5 lSheets-Sheet 5 [Qweno vses having a diameter substantially equal to the interior diameter of the desired lining'with a reduced longitudinally ribbed shank and a short tubular part iltting said shank but having Aa space between it and said mandrel and having an outside diameter substantially equal to the interior diameter of the pipe to be lined. l

3. A pipe lining machine including a mandrel constructed to go through the pipe to be lined and provided with a preceding plastic extruding body, a tube communicating withA said body and carrying it and said mandrel, means for supporting said pipe when telescoped over saidl tube with said mandrel and body through and beyond its end, a plunger fitting said tube, a pushing means engaging said pipe, means for putting plastics in said tube and means for simultaneously advancing s aid plunger and pushing means.

4. A pipe lining machine including a mandrel constructed to go through the pipe to be lined and provided with a preceding plastic extruding body, a stationary tube communicatingly ilxedto said body, means for supporting said pipe for telescopic. movement over said tube, body and mandrel, a plunger fitting said tube, a rod carrying'said plunger, a long carriage constructed to run parallel to said pipe and tube with its front end constructed to engage the former and its rearend ilxed to said yplunger rod, a plastic inlet 'at the rear end of said tube and means'for advancing said carriage.

5. A pipe lining machine including a track,

6. A pipe lining machine including a track, a rack parallel to the front portion oi' said track for carrying the pipe tobe lined, a long end of said carriage'through the slotted portion'- of said guideway and xed to the rear end of said rod and means for moving said carriage.

7. A pipe'lining machine comprising a track, a rack parallel to the front portion of saidtrack for carrying the pipe to be lined, a long carzriage running on said track with its front end adapted to engage said pipe, a tube positioned parallel to the rear portion of said track and having a cross-sectional area equal to that of the thickness oi the desired lining, a plunger in said tube, a rod iixed to said plunger, a mandrel and preceding plastic extruding body on the end of said tube this mandrel having a diameter substantially equal to the inside diameter of the desired lining, a plastic inlet at the opposite end of said tube, an upwardly slotted guideway for said rod, a tongue depending from the rear end of said carriage and ilxed to said rod and means for moving said carriage.-4

8. A pipe lining machine including a mandrel constructed for insertion in thepipe to be lined and which is relatively short as compared to the latter, means for causing relative movement -be tween said mandrel and pipe, and means for extruding a plastic over saidI mandrel at the same linear speed-as that resulting between it and said pipe upon relative movement of the two.

9. A pipe lining machine including a mandrel constructed for insertion in the pipe to be lined and which is relatively short as compared toA the latter, means for causing relative movement between said mandrel and pipe, and means for extruding a plastic over said mandrel at the same linear speed as that resulting between it and said pipe upon relative movement of the two, saidlast named means constantly proportioning the extruded plastic to a predetermined volume per unit oi' length of said'pipe.
